ABSTRACT:
The present invention relates to an apparatus for detecting inserted coins and method thereof in units which are operated by inserting coins such as a vending machine, by using the configuration including the microcomputer for controlling the whole operation to detect the inserted coins, the quality, thickness and diameter detecting sensors for detecting the quality, the thickness and the diameter of the inserted coin and having the method comprising the steps of: counting the time required until the lastly positioned sensor senses the maximum value data after the firstly positioned sensor sensed the maximum value data; performing reset of the apparatus in case that the time required is more than the predetermined time; and discriminating the kinds of the inserted coins based on the quality, the thickness and the diameter maximum value data of the detected coins and the time required, thereby obtaining the advantage that the apparatus stops the operation and is reset when the insertion path is stopped up and that the kinds of the inseted coins are detected more correctly according to the quality, the thickness and the diameter of them.
